Experts at O’Connor

O’Connor’s property tax expertise is deep. We understand both what is taxable and what is not. We understand appeals better than any other firm, based on completing over 1 million property tax appeals. Our team achieves the best property tax appeal results for seven reasons:

  1. Our approach is uniquely aggressive. We appeal every property annually.
  2. We appeal to the highest level of practice every year. O’Connor coordinates more judicial property tax appeals than any other firm.
  3. Our consultants have close relationships with property tax assessors. They know what the assessors require to reduce property tax assessments.
  4. Our appraisal experts understand how to separate real estate from the intangible personal property for hotels, self-storage, medical office buildings, hospitals, emergency care centers, office, retail, warehouse, and apartments. Intangible personal property can comprise a third or more of total value and is not subject to property taxes.
  5. Our tax appeal evidence files are exceptional due to a proprietary national database and a team of 30+ IT professionals. No other U.S. firm has either the database or the large IT team to serve clients at scale.
  6. We are passionate about property tax reduction and understand clients who want us to reduce every property every year. While reductions are not possible every year, this aggressive approach is proven to minimize property taxes.
  7. We measure our success in property taxes saved for our clients—not firm revenues. Enroll in the Property Tax Protection Program™ now to ensure you never pay more than your fair share.
